Be it lnown that 1,; JoHN A. Rrms'vrnon,

n citidu of the United-Stetes, residing at Moragin theoounty of Kanabec and State `of Minnesota, have invented; certain new and usefulglmprovements in Indicating vices for Lubricators; and I do hereby de-E claretlie following tobe exact description oi the iiventiongsuclias which il@ 'minsto ineke undV use the same. L

invention relates" to an autoliobi-le paagticulbto anv-nditin device' for indiehtiig'the wo-pilthrou `the lubricating tube. In automobiles Vof the Eer'd type re is ustoxery provided n. tube haii en open receiving portion at endj i. to receive oil thrown or splashed up f the movingv membersn the cmkcase Y. oil flows byd gravity through tliia lube cnil supplies a lubricating. system."

It is an objnclo this invention to provide afA gauge en findicating means" disposed on the 'dash of tlielautomobile' or within" ton-y venientsight of' the driver for indicating when oil is fiowiig through the `sid supply It is a further object ofthe invention to provide such an indicating-Y meaiis in conection with a clean-out arm or device eppliedtoearidtulxa.4 p j;

It is still another object; of the invemtion to provide suchen indicati l' device coin-Y pkising anoil container in wich the level be varied-'and which contdiner is connected to an air displacement gaugev by asin-all tube. 4

These; and other objects and advantages of the ,invention will be fully 4set forth in (he s u n 'i 1 description made in connec- Gien ,with the accompanying drawings in which like reference charactersvrefer to the parte throughout the dilerent views, and'in which,y l. i

1` is a.: view in side'v elevation vof the vice arts' of the Vengine and case Io t e automobile in dotted 2 ig aviewin vertical section taken mbetntially on theline 2 -2 'of Eig. 1; and "Eigf is a-yiewin front elevaaitionr I ertly in of, the` gauge, kthe same shownY on en enlarged scale.

,Ehm efdeveiofment and improvement of the inapplication 1s-` in one? sense av full, clear, end y um c n c the member 5, a cross-T is is connected to one ofthe 3;" arn preferably in the lli'gifi o in aliriemet'l with ce@ @barema mi closed by e Cep 6. Oef the 1i" of T is arranged to profeet upivridll and pipe or container 7 is screwed intov is al1-nil A T fa pet 8' is above the member and a tlie 9 connected to provided and one of its the ou in the armes. 1f fiigou ewng ijf the tube 1,? the oil will; of retained in thea'rm. andthe ,level ofthe oil in the containerV 7 will besulstaaitially even with the op of et@ aas- ,indicatd b che dotted line c. When oil flows throu th tube 1, the level thev oil in the container 7 will rise to somewhat greater height eitlier at or bove the top of the' tube' 1 at the oint where it isY connected to the 3, 'hislrise of the oil in the container 7 displace the air in seid container, which air the liquid in said gauge vso that the same e will be moved into the tube 9-,and the column of air therein will be moved along into one end of the gauge 11 and will displace will stand higher in one of the arms than in the other. The liquid in the arms-11* of the auge 11 will indicate the level of the oil 1n the container 7 and will thus indicate whether or not oil is flowing through the tube l. In the actual use of the device it has also been found that afterthe oil has been used a long time the same becomes very thin and is of small lubricating value. At such time, the level of the-oil in the tube Z will be loweredeven though oil is traveling through the pipe or tube 1 and the indicating device will thus indicate that the oil is becoming too thin for use. The arms 3 andtube l can be cleaned, as usual, by removing'the cap 6 and inserting a iiexible cleaning element through the member'5 and into the arms 3 and hence, into one portion of the tube 1.V The other arm 3 isused to clean out the other parts of the tube 1,-the arms curving toward the respective ends or ,portions of the tube to guide the cleaning implement into said portions, respectively.v The arms of the cross-T receptacle and will assist in keepin lthe passa e to the container 7- open. `I the use o the gauge is not desired, the pet cock Scanbe opened to affordl a communication from the interior of the container 7 to the atmosphere andthe gauge 11 will thusnot be operated.

From the above description it is seen that i applicant has provided a simple and efficient means for indlcating when the oil through the'oil sup is also ada ted to a for the tu e. simpleVV and can be Ainexpensively made from standard material and easily and uickly atis passing ly tube l, which means ord a clean-out opening tached to a standard automobile o the Fordr or similar type. i

It will, of course, be understood thatL various changes may be made in the form, details and arrangement of the'parts without departing fromA the scope lof applicants invention, which, generally stated,"consists in the matter shown and described and set forth in -the appendedclaims. l
